64-bit divider using Cortex-M3

Mani77 over 3 years ago

Hi ,

I'm trying to do a 64-bit divide operation in C using Cortex-M3.

Is there a reference of optimized assembly code for same or recommended approach?

Thanks

as it's directly implemented by the compiler, I think you can safely assume that it will be well optimised ... ?

The compiler's divide is optimized for the general use case. If you need a special divide, you are free to write your own.
